Component Specifications

Definition
An operational amplifier (op-amp) is an integrated circuit component designed for active filter applications within loop filters, providing high gain, differential input, and single-ended output to implement precise frequency-selective circuits like low-pass, high-pass, band-pass, or notch filters for signal processing in control systems.
Working Principle
Operates by amplifying the voltage difference between its two input terminals (inverting and non-inverting) with high open-loop gain, configured with external resistors and capacitors in feedback networks to create desired filter characteristics such as cutoff frequency, roll-off slope, and phase response, enabling active filtering without inductors.
Materials
Semiconductor silicon die, epoxy or ceramic packaging, gold or aluminum bonding wires, lead frame (typically copper alloy), with specifications including low-noise, high-speed, or precision-grade variants.
Technical Parameters
  • Slew Rate 0.5 V/μs to 100 V/μs
  • Supply Voltage ±5 V to ±15 V
  • Input Offset Voltage 0.1 mV to 5 mV
  • Operating Temperature -40°C to 125°C
  • Gain Bandwidth Product 1 MHz to 100 MHz
Standards
ISO 9001, IEC 60747, JEDEC JESD22
